Ditto what Tempus0 said. I'm playing skirmishes on "manager" and the computers always go for me first. I get bought out the moment that I get 2 advanced factories (glass, chemical, or electronics). I've played multiple strategies to prevent this and the only thing I can do is get lucky enough to have the funds to buy out my stock early, but even that doesn't work because the value of my stock at that point is so low (only $10-12k usually) that they can pay the full price to buy me out.
Here is what you do.
When you start a lobby change game rules to:
1. Reveal map on
2. advanced sabotage on
3. Stock Delay on
And go as Manager. (these are the standard Multiplayer Rules)
Practise 1 Faction at the time. I would suggest that you begin with Expansive > Robotic > Scientific > Scavenger.
Ingame you see a debt Timer that goes off from 150k to 0k. As a beginner you should found atleast <20k debt just to be safe.
When you founded, you first want to have the rescource that are required for upgrades. ( you can see that in the bottom left corner if you hover over upgrade with the mouse)
You get 3 claims to start with:
Expansive: 1 iron((High)in a patch of Iron), 1 Aluminum(High), 1 steel mill.
Robotic: Same as Expansive
Scientific: 2 Steel mills on iron and 1 aluminum
Scavenger: 2 Carbon, 1 aluminum
Try to get the Rescources with the most quantity.
Level 2:
Expansive: 1 Iron, 3 steel mills
Robo: 1 Iron, 2 steel Mills
Scientific: 1 steel mill, 1 water, 1 food (Water and food connected)
Scavenger: 1 water(high!), 2 food
Level 3: This level is to get Power running
Expansive: 1 water, 2 food(change 1 steel mill into food), 2 Geothermal plan (if non on the map go Solar connected to your base)
Robo: 1 water, 2 geothermal plants(or solar)
Scientific: 2 food (change water into food, total food 3), 2 geothermal plants(or solar)
Scavenger: 1 geo and 2 Wind turbines
The food you need to sell down and buy glass with.
And after that look which Rescource is making the most money. Buy into your own stock(atleast 5 stocks) if you want to play safe. Work yourself to an Offworld and gg.
Try out the patent lab/hacker array/Pleasure Dome/Enginering labs on level 4.
